    Abstract: A process for forming a catheter balloon includes subjecting a tubular parison in a mold to molding fluid pressure. The resulting catheter balloon includes a balloon portion having two ends and tubular leg portions extending from either end. The ends of the balloon portion are tapered to the tubular leg portions. The tapered ends have alternating elongate areas of greater and lesser resistance to deformation displaced circumferentially about the tapered ends. The elongate areas of greater and lesser resistance to deformation can include ridges which are either longitudinal or spiraled or rods imbedded in the body of the balloon. While in the mold, the tubular legs are drawn axially sufficiently to form permanent creases in the tapered ends. This drawing may be sufficient to cause the material of the tapered ends to exceed the yield strength, particularly with the balloon material in a malleable state.

    Abstract: A prosthetic apparatus for implantation in a native mitral valve includes a main body for placement within the native mitral annulus. The main body is compressible to a radially compressed state for delivery into the heart and is self-expandable from the compressed state to a radially expanded state for implantation. A valve structure is mounted within a lumen of the main body and preferably forms three leaflets made of pericardium. An atrial sealing member is disposed along an atrial portion of the main body and ventricular anchors are coupled to a ventricular portion of the main body. The atrial sealing member impedes the flow of blood between the main body and the native annulus. The ventricular anchors are positioned outside the main body for capturing native mitral valve leaflets between the main body and the ventricular anchors.

Anomalies on tapered parts of the mold may include ribs or spiral ribs to assist in the creasing process.

    Abstract: Embodiments of a method for implanting a prosthetic valve at the native mitral valve region of the heart, the prosthetic valve including a main body that is radially compressible to a radially compressed state and self-expandable from the compressed state to a radially expanded state. The prosthetic apparatus also comprises at least one ventricular anchor coupled to the main body and disposed outside of the main body with a leaflet-receiving space between the anchor and an outer surface of the main body to receive a native valve leaflet. Apparatus for delivering and implanting the prosthetic valve are also described.
